Accept the surrender

"I except you surrender. You may be a dragon but I am a knight and we fight with honour. Slaying a dragon may bring great fame and riches but there is no honour in killing something that has surrendered. Tell me where is the princess?" You ask

"Thank you, brave knight, the princess you seek lives in the highest tower." The dragon tells you as it gets to work licking its wounds and trying to stop the worst of the bleeding.

Of course, she does (read next bit in a sarcastic tone). After all that, after outsmarting and defeating a dragon, your bruised and battered body has to climb up a hundred stars! You set off towards the entrance of the tower you drop your sword and start climbing.
